Improvement in seed-droppers



PATENT OFFICEu HERMANN KOELLER, OF CAMP POINT, ILLINOIS.

IMPROVEMENT IN SEED-DROPPERS.

Specification forming part of Letters Patent No. 153,576, dated July 2S, 18721; application filed May 16, 1874.

To all lwhom. vit may concern Be it known that I, HERMANN KOELLER, of Camp Point, in the county of Adams and State of Illinois, have invented a new and useful Improvement in Seed- Dropper-s, of which the following is a specification:

Figure l is a side view of my improved device. Fig. 2 is a vertical cross-section of the same, taken through the linex a', Fig. 3. Fig. 3is a top view of the same.

Similar letters of reference indicate corresponding parts.

The invention is an improvement in machines whose seed-slides are operated by a chain-wheel, and a chain extended across the field.

The invention relates to the construction and arrangement of parts, as hereinafter described, and specifically indicated in the claim.

A are two cross-bars, to which the runners or openers and the seed-hoppers are attached, and to the middle parts of which the tongue B is attached. To one or both the cross-bars A is attached a plate or bracket, O, to which are pivoted the small gear-wheel D and the large gear-wheel E, the teeth of which mesh into each other. 'Io the larger gearwheel E is bolted a plate, F, having an eccentric flange or a segment of an eccentric flange formed upon it, which strikes against pins or friction-rollers G, attached to the dropping slide H, so that the said slide may receive a reciprocating movement to drop the seed from the revolutions of the gear-wheels D E. The eccentric F has slots formed in it to receive the bolts by which it is secured to the gearwheel E, so that it may be adjusted to give the dropping-slide H a longer or shorter stroke, as may be desired. To the lower end of the journal of the small gear-wheelD is attached a wheel, I, consisting of four or more radial arms, the outer ends of which are notched to receive a chain, J, and to the lower side of Which'is attached a ring or iange plate, to receive and support the part of the chain J that is passing around said wheel. The chain J is made of long` links, of a length equal to the distance between the notched ends of the arms of the wheel I, as shown in Fig. 3. To the forward side of the ends of the front crossbar A are attached hooks K, to guide the chain as it passes from the ground to the chain-wheel I.

In using the machine, in coming to the end of the field, the driver should slip a springring upon the link that dropped last to the ground, after dropping the last hill before turning, for a mark. He should then count the links that lie crosswise, and put another spring-ring in the link he wishes to begin to drop from, fora mark in starting. After turning around, the flanged chain-wheel I should be set so that the machine will begin to drop at the marked link. This will bring the hills in accurate check-row.

I do not claim the combination in a seeding machine of a chain-wheel, cam, and seed Slide, but e Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The slide H, having fixed friction-rollers G, the slotted iianged eccentric F, secured adjustably to one side of the spur-gear E, which is in turn supported ou the fixed plate C, the revolving pinion D, and the concentric chainwheel I, both iixed ou the same axis, all constructed and combined as shown and described, to operate as specified.

HERMANN KOELLER.
